SHADE-ROLLER.

SPECIFICATION forming part of Letters Patent No. 496,411, dated May 2, 1893.

Application filed January 10,1891. Serial No. 377,345- (No model.)

To all whom it may concern.-

Be it known that I, STEWART HARTSHORN, a citizen of the United States, and a resident of Short Hills, county of Essex, and State of New Jersey,have invented a certain new and useful Improvement in Shade Rollers, of which the following is a specification.

My improvement refers to the gudgeon or journal attached to the end of the roller, and to which revolves with the latter in the bracket; and relates particularly to the class of wooden rollers in which thejournal is driven directly into the end of the roller, or attached to a disk which is nailed or otherwise fastened to the roller. In this class of rollers it is usual to attach this journal after the roller has been cut to fit the window and it thus frequently happens that the journal is not placed in the center of the end of the roller, orin line with the axis of the latter, causing the roller t0 revolve unevenly in its bearings. My improvement is intended to obviate this trouble and insure the placing of the journal exactly in the center of the end of the roller orinline with its central axis.

In the drawings illustrating my invention, Figure 1 is a detached view of my improved gudgeon and end plate, in position to be connected to the roller. Fig. 2 isasectional view of the end plate or disk. Fig. 3 is a side sectional view of the parts shown in Fig. 1 connected together. Fig. 4 is a detached View of a modified form of my improvement. Fig. 5 is a perspective view of the modified form 5 of gudgeon or journal, showing the inner end, or the part which enters the roller. Fig. 6 is a side sectional view of the parts shown in Fig. 4 connected together.

My improvement consists essentially of a disk or plate the same size as the end of the roller, provided with a hole exactly in the center through which the gudgeon or journal passes when connected with the roller, which central hole is so constructed as to direct and guide the passage of the gudgeon and insure its entering the roller exactlyin line with the central axis of the latter.

In the form shown in Fig. 1, the plate or disk a fits over the end of the roller and is provided with ears e which are spread out a little and tend to guide the plate over the end of the roller. In the center of the plate is a projection b which may be stamped up from the latter, and exactly in the center of this projection is a small hole d. The sides of this hole are returned in toward the plate as shown more particularly in Fig. 2. The hole ,d is made just large enough to receive the point of the nail c and the returned sides of the hole act as a guide for the nail and in- 50 sure its being driven exactly into the center of the end of the roller. As this nail is inserted into the opening dand driven into the end of the roller, the hole is enlarged;

the sides of the same bending inward and j Y guiding the nail as shown in Fig. 3. The outer end of the nail c in this form of mydevice constitutes the journal on which the roller revolves. After the plate a is connected to the roller the ears 6 should be pressed close to the sides of the latter and to further secure the end plate, a tack may be driven through one or more of the ears as shown atfin Fig. 3.

In the form of my improvement shown in Fig. 4, the inner end of the attaching device 0 forming the journal, where the same enters the end of the roller, is made hollow as shown in Fig. 5 and the opening 61 in the end of the plate is just large enough for the end 0 of the journal to easily enter the same. As the journal is driven into the wood the sides of the opening are bent inward as in the form of construction shown in Fig. 6. In this form of my device, the part of the journal which enters the wood surrounds or incloses a sec; tion of the latter and insures a broad bearing in the roller for the journal.

In my improved journal or gudgeon, the end plate a is formed just the size of the end 0 of the roller and consequently the journal itself when passed through the central opening in the plate, must be on a line with the axis of the roller and thus insures a true bearing of the latterin the bracket. And 5 moreover, one nail or fastening device is necessary to attach the plate and journal to the roller and the central opening in the plate is of such a nature as to act as a guide for the nail and insure its entering the roller in the too center of the end of thelatter in line with its axis.

What I claim is- 1. In a gudgeon for shade rollers the 00111- 5 bination with the gudgeon pin 0 having a point on its inner end, of the disk at having the raised central portion b and central hole (1 with returned sides adapted to fit the point of the pin 0, and the flanges e, whereby when 10 the point of the pin is fitted into the hole 61 and the pin driven into the roller, the sides of the hole will be turned in and guide the pin into the roller, substantially as described.
